Dear All,

I used the core 4507R with main frome token SNA application from other vlans but failed the SNA application.So the fallback bridge option not there.

I used the 3560 switch then all floor vlans are conencted to the main frame SNA.

Is there any work around to use core 4500 for fall back bridge.

Cisco TAC confirmed me that 4500 would not support Fall back bridgeing.

Please provide the solu since the core switch sold to the customer already.

Even though I do not recommend this, you could physically loop back ports to emulate bridging. Say for example, you want to bridge between VLAN 10 and 20. Configure a port in VLAN 10 and another port in VLAN 20 and connect these 2 ports via a cross over cable.
